Some NSFNET-sponsored networks may have agreements with other network providers
(e.g. CIX or ANS) to exchange traffic with networks in these countries. That traffic
is not included in the reports found in the /nsfnet/statistics directory on nic.merit.edu.

No route filtering (except as stated above) is in place for any other networks
announced on the ANSNet backbone. For a list of networks whose announcement
is through ANS CO+RE, see the file /nsfnet/announced.networks/ans_core.now on nic.merit.edu.
